hhhmm I have had the ip packet part once and the ip packet is nothign to worrie about and if that chat was in-game get an anti spammer, the anti spammer will help your server from crashing by people spamming over and over again that fast

"188.37.36.179:64589" Do you see this smartass? Simply, firewall his IP so he won't be able to see the server online.

That is someone who is spamming your server and they know where the server is weak at, Ban the IP and Try and get a IPblocker.

You server crashed because you using zcmd, and attacker send a packet with NULL command. This is zcmd bug, just add a cmdtext check for NULL
PHP код:
if(!cmdtext[0]) return Ban(playerid); // because it's impossible to send valid NULL command
